CryptoAES

public CryptoAES(String transformation,
                 Properties properties,
                 byte[] inKey,
                 byte[] outKey,
                 byte[] inIv,
                 byte[] outIv)
          throws IOException

抛出:

IOException

方法详细资料

wrap

public byte[] wrap(byte[] data,
                   int offset,
                   int len)
            throws SaslException

Encrypts input data. The result composes of (msg, padding if needed, mac) and sequence num.

参数:

data - the input byte array

offset - the offset in input where the input starts

len - the input length

返回:

the new encrypted byte array.

抛出:

SaslException - if error happens

unwrap

public byte[] unwrap(byte[] data,
                     int offset,
                     int len)
              throws SaslException

Decrypts input data. The input composes of (msg, padding if needed, mac) and sequence num. The result is msg.

参数:

data - the input byte array

offset - the offset in input where the input starts

len - the input length

返回:

the new decrypted byte array.

抛出:

SaslException - if error happens
